the acceleration of a rolling ball or cart depends on the ramp angle. Then‚ you will use your data to extrapolate to the acceleration on a vertical “ramp;” that is‚ the acceleration of a ball in free fall. If the angle of an incline with the horizontal is small‚ a cart rolling down the incline moves slowly and can be easily timed. Using time and position data‚ it is possible to calculate the acceleration of the cart. When the angle of the incline is increased‚ the acceleration also increases. The

straight line of known length related one another by known angles between the line. The points defining the ends of the traverse lines are called traverse stations. Traverse survey is a method of establishing control points‚ their position being determined by measuring the distances between the traverse station which serve as control points and the angles subtended at the various stations by their adjacent stations. The angles are measured using theodolite and the distance measured by

obtain twist angles and maximum stresses for specific lamina wind up angles. The report will provide analysis of the methods used to obtain these criteria. AIM Use a Mathcad script to determine the procedure used during the manufacture of a wound laminate composite tube and to assess its validity for use in stress and strain analyses.

bridge and rail 4. Perimeter fence 5. Grass. Decking and Border The decking area consists of two right angle triangle. The two edges around the decking are equal in length. I need to work out the length of the edges and the area of the decking‚ how much materials required and cost. In the 1st triangle marked A‚ I need to work out the length the opposite side of the triangle with the angle 69º. I will do this by using trigonometry tan equation. Tan ɵ = Tan 69 = If I subtract 4m from the above

Now fold down the top corners inward to the center crease along the dashed "valley folds" shown‚ making two new right-angle triangles visible in illustration 4. 4. Fold the large top triangle (made up of the two small triangles you just created in step 3)‚ over and down. 5. Fold the lower part of the tip of the large triangle up again. But note - not quite all

Chris Crouse‚ Juan Agosto‚ Bianca Butler‚ Hunter Zaun Feb. 12‚ 2013 Mrs. Rarig Physics Projectile Range Versus Angle Intro: First off‚ what projectile motion is motion in two dimensions in both X & Y directions. The only force on the projectile is gravity. With gravity being a presence and a factor in our everyday lives and in this experiment‚ gravity will push down on the projectile forcing it back down to the ground. For example if someone shot a cannon straight and there was no gravity

Chapter 8- Circular Measure Additional Mathematics Module Form 4 SMK Agama Arau‚ Perlis CHAPTER 8- CIRCULAR MEASURE 8.1 RADIAN 1. In lower secondary‚ we have learned the unit for angle is degree. In this chapter‚ we will learn one more unit for angle that is radian. P r O 1 radian r Q 2. When the value of the angle 1 radian‚ then the length of the arc is equal to the length of the radius. 3. From this information‚ we can deduce that: r 1 rad r = 360 2πr 1 rad = r 2πr × 360 2π rad = 360°
